Watch for persistent changes in bowel habits, blood in or on the stool, unexplained abdominal pain or cramping, a continuing sensation that you need to have a bowel movement, unexplained weight loss, and unusual weakness or fatigue. These symptoms can have many causes besides cancer, but they should not be automatically ignored. ([Cancer.org][1])
For people at average risk, regular colorectal cancer screening generally begins at age 45 under current American Cancer Society recommendations. People with higher-risk medical or family histories may need a different screening plan. ([Cancer.org][7])
The message is not “every digestive symptom means cancer.”
The message is pay attention to persistent changes, know your risk, and get appropriate screening.
Early detection can make a meaningful difference, and screening can sometimes prevent colorectal cancer altogether by identifying precancerous polyps before they become cancer. ([Institut National du Cancer][2])
If you are experiencing concerning symptoms, speak with a qualified healthcare professional rather than trying to diagnose yourself online.
